Abstract
The invention provides a die structure adding a thimble on an inclined top, which enables ejection of thinner side wall of a product and separation of the product and the contact surface of the product to be carried out separately, so that the thinner side wall of the product does not deform or strain easily and the yield of the product is further improved. The die structure comprises a front die, a rear die and the inclined top, wherein a cavity is formed between the front die and the rear die; the product is arranged in the cavity; after the top part of the inclined top penetrates through the rear die, one side surface of the inclined top is fitted the thinner side wall of the product. The die structure is characterized in that the thimble and a thimble spring are arranged in the inclined top; the front part of the thimble penetrates through the inclined top and then is propped and mounted at the thinner side wall; a spring mounting groove is formed in the inclined top, the thimble spring is positioned in the spring mounting groove, and two ends of the thimble spring are propped and mounted on the front end surface of a lug boss at the tail part of the thimble, and on one side, close to the thinner side wall, of the spring mounting groove respectively.
Description
Technical field
The present invention relates to the technical field of structures of product mold, be specially the mould structure that adds thimble on a kind of oblique top.
Background technology
The existing product of producing with mould, much all adopt the oblique top mould unloading structure, but some product is thinner with the sidewall of inclined top face contact, during the demoulding, because product ejects, product and oblique top contact-making surface break away from simultaneously and occur, the power that makes the sidewall thin location of product simultaneously bear two side directions, make the sidewall thin location easily deform, pull, and makes the defect rate of product high.
Summary of the invention
The invention provides the mould structure that adds thimble on a kind of oblique top, it makes the ejecting of sidewall thin location, product and the oblique top contact-making surface of product break away to carry out separately respectively, guarantee that product sidewall thin location is difficult for deforming, pulling, and then the yields of improving product.
The mould structure that adds thimble on a kind of oblique top, its technical scheme is such: it comprises front mould, rear mold, oblique top, described front mould, it between rear mold, is die cavity, in described die cavity, it is product, after described rear mold is run through on described oblique top top, the fit sidewall thin location of described product of one side, it is characterized in that: the inside of described oblique top is provided with thimble, the thimble spring, the front portion of described thimble is mounted on described sidewall thin location after running through described oblique top, have the spring fitting groove in described oblique top, the thimble spring is positioned at described spring fitting groove, the two ends of described thimble spring are mounted on respectively the tail protrusion section front end face of described thimble, one side of the close described sidewall thin location of spring fitting groove, leave gap between the side away from described sidewall thin location of the tail protrusion section rear end face of the described thimble under the matched moulds state and described spring fitting groove, the top of oblique top gathering sill end face is the arc structure away from described sidewall thin location, the mid portion of described oblique top gathering sill end face is vertical plane, the tail end of described thimble exposes to the another side of described oblique top, the matched moulds state and not fully during the demoulding tail end of described thimble be close to the vertical plane of the mid portion of described oblique top gathering sill end face.
It is further characterized in that: described oblique top is equipped with wear-resistant block corresponding to described oblique top gathering sill endface position, described wear-resistant block, oblique top coordinate fastening installation to form the spring fitting groove, and the tail end of described thimble exposes to described wear-resistant block and is close to the vertical plane of mid portion of the oblique top gathering sill end face of described rear mold.
After adopting structure of the present invention, not fully during the demoulding, the tail end of thimble is close to the mid portion of described oblique top gathering sill end face, the mid portion of oblique top gathering sill end face is vertical plane, its front portion that makes thimble is the sidewall thin location of sticky and product all the time, until after the complete demoulding, the tail end of thimble is along arc structure outwards motion under the pressure-acting of thimble spring of the sidewall thin location away from product, leave gap between the side away from the sidewall thin location due to tail protrusion section rear end face and described spring fitting groove, it is the anterior indentation of thimble, oblique top continues to rise afterwards, make product and oblique top contact-making surface break away from, it makes the ejecting of sidewall thin location of product, product and the disengaging of oblique top contact-making surface are carried out separately respectively, guarantee that product sidewall thin location is difficult for deforming, pull, and then the yields of improving product.
The accompanying drawing explanation
Fig. 1 is front view structural representation of the present invention.
